ERn Ethernet Switch Module Installation

The ERn Ethernet Switch module installs in the bottom option module tray of the ERn enclosure, replacing
the blank module that ships in the ERn from the factory. The bottom option slot is the only position for the
Ethernet switch module.

Note:

The Ethernet switch module (ERn-NET) is not designed for use in a rack mounted ERn
unit. Instead, utilize a rack mounted Ethernet switch (provided by others).

Additionally, the ERn-NET is not supported in an ERn4 enclosure at 230 VAC.

The ERn Ethernet switch (ERn-NET) provides four ports of Power over Ethernet (PoE). The ERn Ethernet
switch kit includes an option module, Ethernet patch panel, Ethernet switch panel, and B Ethernet patch
cables.

The Ethernet patch panel includes four punch down terminal blocks that accept CAT5e wire. Building wire
enters the ERn enclosure and terminates to this patch panel. For each Ethernet data run, an Ethernet patch
cable is provided to connect between the Ethernet patch panel and the Ethernet switch panel.

Install the Ethernet Switch Option

1: Install the Ethernet patch panel to the mounting studs on the rear panel of the ERn enclosure using

the hardware provided.

2: Install the Ethernet switch panel to the mounting studs on the bottom panel of the ERn enclosure

using the hardware provided. Be sure to install the panel with the card edge receptacle facing the
front of the ERn enclosure.

Connect CAT5e Wiring

Note:

1: Pull your CAT5e building wire through the conduit access previously prepared.

2: Use a slotted screwdriver to remove the Ethernet punch down connector from the Ethernet patch

panel and remove the connector covers from each side to reveal the connector terminals. The punch
down connector provides insulation displacement therefore stripping of wire is not required.

All Ethernet terminations must follow IEEE 802.3 and be terminated to the T568B
standard.

3: Reference the connector label for the CAT5e wire termination color code.
4: Use a 110 punch down tool (not provided) to complete the wire termination and replace the

protective covers over the wire terminals.
5: Replace the punch down connector in the patch panel.
6: Connect Ethernet patch cables.

a: Connect a patch cable from the left I/O to the first RJ-45 input on the Ethernet switch panel.

b: Connect a patch cable from the punch down connector to an RJ-45 input on the switch panel.

Repeat for each building service connection (up to four).
